Spontaneous Scoto-leptogenesis
Arghyajit Datta, Hyun Min Lee, Jun-Ho Song
We propose a low-scale spontaneous leptogenesis scenario within the dynamical minimal scotogenic model for accommodating neutrino masses and inert scalar dark matter simultaneously…
Cogenesis of baryon and lepton number asymmetries matching the EMPRESS Data
Kyu Jung Bae, Arghyajit Datta, Rinku Maji +1
We show that a simple supersymmetric extension of the standard model can explain simultaneously the large electron neutrino asymmetry hinted by the recent EMPRESS data…
Probing Right Handed Neutrino assisted Reheating with Gravitational Waves and Leptogenesis
Arghyajit Datta, Shaaban Khalil, Rajat Kumar Mandal +1
We investigate a non-instantaneous reheating period in the early Universe, where the inflaton field decays exclusively to right-handed neutrinos (RHNs). The subsequent decay of the…
Is leptogenesis during gravitational reheating flavourful?
Basabendu Barman, Arghyajit Datta, Md Riajul Haque
We examine the impact of charged lepton Yukawa equilibration on leptogenesis during gravitational reheating. During the post-inflationary era, the inflaton field is assumed to osci…
Probing leptogenesis and the minimal neutrino seesaw mechanism through gravitational waves
Arghyajit Datta, Arunansu Sil
We propose that a gravitational wave can be generated during leptogenesis in the early Universe which occurs during heavy right-handed neutrino decay. Such a gravitational wave, as…
Spontaneous Leptogenesis with sub-GeV Axion Like Particles
Arghyajit Datta, Soumen Kumar Manna, Arunansu Sil
A derivative coupling of an axion like particle (ALP) with a B-L current may lead to the baryon asymmetry of the universe via spontaneous leptogenesis provided a lepton number brea…
Testing Axionic Dark Matter during Gravitational Reheating
Basabendu Barman, Arghyajit Datta
Assuming axions are potential dark matter (DM) candidate that make up all of the DM abundance, we discuss production of axions via (i) standard misalignment mechanism during the pe…
Leptogenesis from a Phase Transition in a Dynamical Vacuum
Dipendu Bhandari, Arghyajit Datta, Arunansu Sil
We show that a phase transition may take place in the early Universe at a temperature via a Standard Model singlet scalar field which happens to couple to right handed neutri…
Flavor Leptogenesis During Reheating Era
Arghyajit Datta, Rishav Roshan, Arunansu Sil
Recently, it has been shown that the presence of a non-instantaneous era of reheating can significantly alter the charged lepton(s) equilibration temperature(s) which plays importa…
On the distribution of polynomials having a given number of irreducible factors over finite fields
Arghya Datta
Let be a fixed prime power. We prove an asymptotic formula for counting the number of monic polynomials that are of degree and have exactly irreducible facto…
Effects of Reheating on Charged Lepton Yukawa Equilibration and Leptogenesis
Arghyajit Datta, Rishav Roshan, Arunansu Sil
We show that the process of non-instantaneous reheating during the post-inflationary period can have a sizable impact on the charged lepton Yukawa equilibration temperature in the…
Scalar Triplet Flavor Leptogenesis with Dark Matter
Arghyajit Datta, Rishav Roshan, Arunansu Sil
We investigate a simple variant of type-II seesaw, responsible for neutrino mass generation, where the particle spectrum is extended with one singlet right-handed neutrino and an i…
Flavored Leptogenesis and Neutrino Mass with Symmetry
Arghyajit Datta, Biswajit Karmakar, Arunansu Sil
We propose a minimal flavor symmetric model, assisted by symmetry, which can naturally takes care of the appropriate lepton mixing and neutrino masses via Ty…
Imprint of the seesaw mechanism on feebly interacting dark matter and the baryon asymmetry
Arghyajit Datta, Rishav Roshan, Arunansu Sil
We show that the type-I seesaw, responsible for generating the light neutrino mass, itself is capable of accommodating one of the three right handed neutrinos as a freeze-in type o…
